On the Transferability of Knowledge among Vehicle Routing Problems by using Cellular Evolutionary Multitasking

open access: yes, 2020
Multitasking optimization is a recently introduced paradigm, focused on the simultaneous solving of multiple optimization problem instances (tasks). The goal of multitasking environments is to dynamically exploit existing complementarities and synergies ...

Enhancing post‐fire decision‐making: a framework for rapid wildfire impact assessment and evidence‐based management planning

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Altered wildfire regimes, exacerbated by unsustainable management, threaten natural ecosystem recovery post‐fire. Effective restoration requires timely fire impact assessments and tailored, evidence‐based management. While fire databases and Environmental Impact Assessment (EIA) frameworks partially support decision‐making, a ...

Perceptivni distraktori utječu na reprezentacije vidnoga radnog pamćenja samo u ranim fazama obrade

open access: yesPsychological Topics, 2022
Jedan je od glavnih zadataka vidnoga radnog pamćenja (VRP) zaštita pohranjenih sadržaja od nevažnih vidnih podražaja u okolini, tj. od distraktirajućih informacija. Iako velik broj istraživanja pokazuje negativan utjecaj distraktora na sadržaje u VRP-u,

Tackling Dynamic Vehicle Routing Problem with Time Windows by means of Ant Colony System

open access: yes, 2017
The Dynamic Vehicle Routing Problem with Time Windows (DVRPTW) is an extension of the well-known Vehicle Routing Problem (VRP), which takes into account the dynamic nature of the problem.

A Heavy‐Duty Vehicle Routing Problem With Temperature Constraints

open access: yesNetworks, Volume 87, Issue 2, Page 131-150, March 2026.
ABSTRACT This article studies a vehicle routing problem involving a fleet of heavy‐duty vehicles and pickup‐and‐delivery requests for crude items that are both heavy and high‐temperature. The objective is to route the fleet in such a way that maximizes resource efficiency and operational efficiency while simultaneously avoiding thermal overload of any ...

PyVRP: A High-Performance VRP Solver Package

open access: yesINFORMS Journal on Computing
We introduce PyVRP, a Python package that implements hybrid genetic search in a state-of-the-art vehicle routing problem (VRP) solver. The package is designed for the VRP with time windows (VRPTW) but can be easily extended to support other VRP variants.

Subset‐Row Inequalities and Unreachability in Path‐Based Formulations for Vehicle Routing and Scheduling Problems

open access: yesNetworks, Volume 87, Issue 2, Page 111-130, March 2026.
ABSTRACT This work considers branch‐price‐and‐cut algorithms for variants of the vehicle‐routing problem in which subset‐row inequalities (SRIs) are used to strengthen the linear relaxation. SRIs often help to substantially reduce the size of the branch‐and‐bound search tree.

Capacitated Vehicle Routing Problem with a Zone Tariff

open access: yesNetworks, Volume 87, Issue 2, Page 210-227, March 2026.
ABSTRACT High demand and volume fluctuations, constrained transportation capacity, and weak network effects compel retailers to rely on external logistic service providers (LSPs) instead of operating their own transportation fleet. This outsourcing process requires retailers to propose tours to LSPs that then carry out the store deliveries.

Asymmetric information of variance risk premium in the Chinese market: upside and downside volatility spillovers

open access: yesManagement System Engineering
We investigate the degree of asymmetry in the variance risk premium (VRP) using SSE 50 ETF options in the Chinese market. Our approach decomposes the VRP into upside and downside components and quantifies the dynamic spillover asymmetry measure (SAM ...
